This is so overrated.. Depending on species, some only breed once a month..so if 1 escapes you could have millions next month.
Those american roaches are truly pest.. Those are killed on sight lolyeah
if you are in an area where american cockroaches thrive, i wouldnt even try cos they can spread and take over!
but there are many roaches overseas (you guys are lucky) in nz, we have little to no big radily avial roaches.
i heard that dubia roaches are easy to contain and breed or raise. also gutloading them is so easy.
if i could i would!
i would feed pellets, spirulina and sweet potato to gutload and feed that.
